This paragraph applies where the qualifying person (P) states under paragraph 11(a) that family benefit contributions are to be paid by Method 1.
Where this paragraph applies, except as otherwise provided in Part 2, P must pay family benefit contributions to the Secretary of State by way of monthly payments from P's contributable salary at the percentage rate specified under paragraph 11(a) or, where the rate is varied under paragraph 20(1), at the specified higher rate for the duration of the payment period.
Except as otherwise provided in Part 2 the payment period (in years and fractions of a year) is A/B × C, where—
A is the period (in years) specified under paragraph 10,
B is the percentage rate specified under paragraph 11(a), and
C is the multiplier determined from time to time by the Secretary of State (after taking advice from the scheme actuary) for the purpose of this Part for a person of the same sex as the qualifying person's beneficiary (as defined in paragraph 9).
